@WANGJIAWEI999 This doesn't appear to be a MetaMask bug. Developer support requests should be directed to the Ethereum Stack Exchange group:

Reopening this, as this is a problem with the MetaMask extension build system.

We don't use Windows for development as a team, but I think we should support development on Windows to help community contributors at least.
